    Volvo Penta 4.3 GL No Power to Fuel Pump

    Thanks got it sorted out, I grabbed another relay off a cracked engine and that ended up being shot as well. Replaced it with another and now I have 12V running to the yellow/red wire on the pump. Do you know by chance if the electrical wiring is marine specific? I want to fix this harness as...

    Volvo Penta 4.3 GL No Power to Fuel Pump

    Yes so I had 12V on the orange/green pin. The orange wire individually only had 12V and the green did not have any voltage. It's possible the other relay I put was shot as well. I'll have to check with a new one. Getting it towed in today with the sellers other boat so I'll finally be able to...

    Volvo Penta 4.3 GL No Power to Fuel Pump

    I'll check it out and get back to you on the model Friday. Not entirely sure what it is. I just know it's a 1996 Model from the old style trim cylinders it has on it and the side mounted raw water pump. This should be close enough to the engine I have, it's a 4.3GS model carbureted. 4.3GSPNCA...

    Volvo Penta 4.3 GL No Power to Fuel Pump

    No idea, they had some "mechanic" that did work on all their boats at this boat club/STR property company and I picked up two boats from them. One of the boats has a cracked block which I was aware of and the other just had this fuel delivery issue. Other ones harness is untouched and this one...

    Volvo Penta 4.3 GL No Power to Fuel Pump

    Ok, I just wanted to solve this crap if it was more or less accessible to change out the diodes or whatever the issue is. I have an standalone gas tank with a squeeze bulb on it. I did hotwire the pump to check if it would work that's about it. Just don't know if that pump is continuously on...

    Volvo Penta 4.3 GL No Power to Fuel Pump

    Sorry not 12V I checked the positive wires and they all had 12V, just not the fuel pump yellow/red wire. Would I just check continuity on either side of the green and orange wire where the diode is to see the reading for it? I'll check resistance next. Just need to youtube a video to double...

    Volvo Penta 4.3 GL No Power to Fuel Pump

    Yup, a cluster of garbage. I just need it to run enough to get me to the boat ramp on the other side to put on my trailer. I have a harness sitting for the boat at the warehouse.

    Volvo Penta 4.3 GL No Power to Fuel Pump

    I'm getting no power to the fuel pump, if I put direct power to the fuel pump it will run. Engine starts after pumping the throttle several times and stays running obviously until gas runs out. I checked power at green wire on the alternator and I am getting 12V. I checked power to the green...

    Kohler 5E Generator crank/no start K2/3 lit up

    I have a couple of these generators, last one I pulled a few weeks ago and did the same maintenance and repairs started after a few times pressing the on button and manually pumping the throttle on the carburetor. I'll have to check spark on it in just a few minutes. I just don't hear the fuel...

    Kohler 5E Generator crank/no start K2/3 lit up

    All I have on the generator is a stop/start switch and a breaker for on/off position. Not aware of any preheat on these carbureted gasoline generators.

    Kohler 5E Generator crank/no start K2/3 lit up

    I changed out the plugs, water pump impeller, bushing behind water pump, and a few other things. I just haven't changed out the fuses for the relays. I'm assuming it's the control board or the sensors on it, however if it was the sensors it would at least start. I'll start out by changing the...

    Kohler 5E Generator crank/no start K2/3 lit up

    I have my generator out on a pallet after I did maintenance, resprayed it and changed out the rusted out pan to a stainless steel one. I never had this generator started before as it's just out of a project Regal Commodore. I have it hooked up to a hose and a battery on a standalone gas tank...

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    Awesome, that worked like a charm. I'm assuming I would just splice these connections together correct or do they make a female plug that jumps the connection?

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    If you can send me what connections need to be jumped since I detached the transmissions to list one of these 8.1s for sale and one for install that'd be great.

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    It did have a ZF 63 transmission attached. I think that might be my issue then! I started the other engine when the transmission was attached still... I can't believe I missed it. Do I need to change anything electrical since I'm converting it for a sternboard? I have the other engine I will be...

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    The only spot that I did not have 12.4/.5 Volts going to was the red/yellow connection at the slave relay and where the red/yellow wire leads to on the starter solenoid. Every other connection with the yellow/red wire had 12V to it and I checked the positive connections at the starter, slave...

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    It's a 2003 engine, it has the 3 square relays. There's no relay with a yellow/red wire going to it. I swapped over 3 relays from my other 8.1 with the 3 on this engine. Still the same issue, that engine starts. I have the wiring diagram for this engine and there's a yellow/red going from the...
